' Application filed June 18, 1927. Serial No. 198,525. i

Our invention relates to a new and useful 1 improvement in liquid dispensers, and more chine.

particularly to a dispenser that is t0 be usedin conjunction with a clothes washing ma- .In the large washing'inachines used in commercial laundries, dlfi'erent. arrange-' ments are provided for intermittently feed-- ing different materials and liquids to the washin and bleaching liquids, and liquids remain in the clothes washer for only a certain length of time. *The washer is then flushed or emptied so that freshbatches of water and liquids and other materials may be added. v

The present invention provides a means for dispensing a predetermined amount of liquid'to the washer and to further provide means whereby there will be no continuous or intermittent drip between the feedings of the liquid to the washer. r

Still another object of the inventionis to provide a dispenser that is intermittently I arrangements and combination of parts as will be hereinafter more fully described and means 14 within the and automatically operated, the present invention having to do with the actual dispens- I ing mechanism" and the manner in which it is arranged so that. when the automatic mechanism operates for tripping the dispenser,the

dispenser will feed and then-drop back a preso that there will be no i dripping of the liquid between its operations. for operating the above for applying the power at stated intervals 'to this mechaf-= nism'forms the subject matter of a'separate determined distance,

v The actual means mechanism,'that is, the means application.

Still another object of the invention' isto provide a simple liquid dispensing'mechiu' predetermined amountnism that will feed a of liquid to the washer, and at the same time will prevent any drip betweenorafter each of the dispensing movements. v

With these and other objects in view, the invention consists in certain'new and novel pointed out in the claims. i V 1 Referring now to the drawings, showing a preferred embodiment of our invention, R

Fig. 1 is a side elevation showing the 0 machine, such as soap, bluing, sour, all of which materials" Y certain'limits.

ratchet movement for operating the bucket, the bucket being shown in section. I Fig. 2 is a front elevation of the mechanism shown in Fig. 1, and

Fig. 3 shows a slightly modified form of ratchet movement for operating the bucket. Referring now more specifically 'tothe several views, there isshown a bucket or tank 1, having approximately the shape of a quadrant. This bucket or tank' may bea' casting or may be formed of thin sheet metal, and provided with metal'ribs 2, there being 7 formed a slot or bearing 3at the center of the radii of the bucket. This 'bearingis' pro vided with the overhanging'lip 4 so that as Y the bucket is oscillated about an axial shaft 5, it will always be 'pivotally-and. centrally supported. r p This shaft 5 will be supported in thefarms' 6 which are shownfragmentarily in' Fig; 2,, 7 these arms, of course, being long enough to l permit an oscillation of the bucket about the axial shaft 5. i r

This bucket is preferably provided with a lug 7 at the lower edge of its front or verti" cal face, so that a small rope or cable 8 may pass around the arcuate portion andbe fastened at its upper end-about the small 'drum 9, which in 'turn is fixedly secured on the small shaft 10 mounted in the frame 11, whileh frame is also shownfragmentarily; "f 7 To the other end of this shaft lO-is mounted the upright'arm-l2 provided with the slot 13 in its upper end in which slot there may be movably bolted a hook or eyelet 14to which, in turn, will then be-secured a rod'or rope '15 which is adapted to extend to a power mechanism for intermittently pulling and leasing this rope15 to in turn move the arm 12 and let it return. j

In another application there'is-shown and. described the means for intermittently oper-* .ating this cable or rod 15, it being suflicient" I in this application to'state that attimed intervals a pulling force is applied to this cable 15.; v f By providing the slot 13 and the securing slot, the length of the throwofthe arm 12 may be regulated 5 Referring again to the arm 12, there will i be seen a small lug 16 to Which there is pivoted a small actuating pawl 17 which in turn mounted'on the shaft 10.

is designed to cooperate with the teeth 18 on a ratchet wheel 19 which wheel fixedly of the teeth 18 will advance the ratchet wheel 19 to revolve the drum and thus slightly raise the bucket 1. y I

It is to be understood'that the length of movement of the cable 15 will be predetermined'as Well as the throw of the arm 12,so that a movement or pull on the cable 15 will advance the arm 12 and revolve the ratchet a predetermined amount.

'Means have to be provided, however, to prevent any drip from the bucket after each operation, as otherwise the water level would ing machine. I

WVe have, therefore, provided means wherealwaysbe just even with themouth of the bucket and would continue to drip, especially with'any jarringiof the machine, and this would be a disadvantage as at certain times it would not be desired to haveany of the' liquid from this d ispenser, whatever it may be, dropping from this bucket into the washby the bucket isoscillated or. raised a predetermined amount, so that the liquid, that is,

a certain amount,'will spill out of the same after which the bucket is allowed to. swing back slightly, so that the water level in the tankwill be slightly below the mouth of the bucket. J

To accomplish this, s we provide a second pawl 21 (holding pawl) which isheldincontact with theratchet teethby 'the'spring 22 v as "may be seen in Fig. 1.

f The size of-the ratchet teeth 18 is in a oertain ratio with the throw of the arm 12 and the disposition of the pawl 21 issuch that as the arm 12 moves forwardly when operated, -it will advance the ratchet wheel one and three-fourths teeth. The pawl 21 is so disposed that it will come to'rest onthe slope of a tooth rather than against the face of the tooth and the weight of the tank on the drum will causethe ratchet wheel to slip rearwardly until the pawl 21'engages the face of the oncoming tooth.

the distance of three-fourths of a'tooth,

I This slip is practically three-fourths of'the length of the tooth. In 1 other words,'on each movement or throw of the. arm 12, the ratchet wheel will slip back From this it will be seen that the bucket or container will be elevated a slight distance to spill a predeterminedamount of liquid, after wh1ch spilling the bucket will drop a slight v distance, that is, a distance in proportion to the slip for three-fourths of the length of a tooth. I p

Eventuall the drum 9 will wind up enough of tie cable to emptyvthe bucket or container, after which, of course, it will again be reset and filled withthe desired liquid.

It will also be seen that as the bucket revolves a predetermined amount about the axis 5, and as the shape of the bucket is a quadrant, the same amount of liquid will be dispensed each time, regardless of how full the bucket is or what its position. V

The-water level, right after the dispensing movement, will be slightly below the mouth of the bucket, so that there will be no drip between operations. I

' In Fig. 3 we have shown a slightly modified form for elevating the bucket in a step by step movement and also to allow the bucket to lower slightly immediately after its elevation, so that the water level with this form of operating mechanism will always be slightly below the mouth'of the bucket between the dispensing operations, and therefore prevent any undesirable dripping. a

In this form, the bucketanddrum are'the same, but theratchet wheel 23 may be provided with slightly smaller teeth 2e than in the wheel 19. The same kind of operating lever or arm 25is shown loosely mounted on the shaft 10. There'is also a pawl 26 attached to this arm, andlikewise a'slot 27 is shown in which there is a bolt 28 to which isfastened the cable 29 and to which isalso fastened a small spring 30. The throw, therefore, can be regulated by securing the bolt28 at adif ferent positionup and down the slot 27.

Now, thehold'ingpawl 31is slightly differentv from the holding pawl21'in that it is provided witha slot 32 at its lower end sothat it may ride-aswell a s pivot onthe pin 33.

- This'pawl has th'e1tooth34 tolengage the 'ratchetteeth 24:, and is provided with the small arms 35 on its end to straddlethe ratchet .wheel 23 so that the pawl will never slip off the wheel 23.

As'before mentioned, the ratchet wheel'and drum arefixedly secured on the shaft 10 so that an operation of the cable 29iby a mechanism (not shown) will advance the arm 25 and move or revolve the ratchet wheel the length of the stroke'of the arm. 7 This will elevate the bucket a predetermined amount through the cable8, but instead of the pawl 31 slipping over a tooth as in the former instance, it will immediately engage one of the teeth 24 and as soon as the cable 29 is released so that the arm-25 swings backwardly, it will allow the ratchet wheel to slip back the length of the slot 32 in the pawl 31, where-,of course,

it willhold the ratchet from the further movement. I

'Thus, it willcbe seen that every time the cable 29 is operated, it will raise the bucket a slight, amount, rather revolve-the bucket a slight amount, to thus spill-"or dispense an amount of liquid, afterwhich the bucket will dripping between. the operations, which dripping might spoil the proportions of the various liquids or chemicals in the washer.

It will also be seen that theaction is posi-' tive; that the mechanisms are not complicated, and the device is one that may be quickly assembled and readily operated.

The bucket might be of other desired shape, just so it performs the same functions in the same manner.

Many slight changes might be made without in any way departing from the spirit and scope of the invention.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1.
